, folders from the stitching machine 1 as they are stitched and released therefrom.

The framework of the folding machine 2 comprises four standards 3 resting on any suitable base not illustrated in the drawings. The standards 3 at either-end of the machine are bridged at the top by horizontal bars 4, these crossbars preferably being formedintegral with the standards 3. Intermediate the ends of the standards 3 and below the cross bars 4 are bracing rodsor bars 5, these also being preferably formed integrally with the standards. Intermediate bars l and 5 there areadditional bracing bars 6 which extend lengthwise of the machine and at right angles to the bars 4 and 5 and are also formed integral with the-standards 3, the standards 3 and cross bars 4, 5 and 6 thus forming a rigid frame work for the support of the different mechanisms.

Extending rearwardly from the machine and to a point adjacent the forward end thereof there is mounted a saddle 7, this saddle being of the usual \l-shaped form with its apex turned upward and being in alinement with the saddleof the stitching and stapling machine 1. The saddle may be conveniently supported by means of a bracket 8 extending upwardly from the rear cross bar 5 and at its front end by a similar upright standard not illustrated in the draw ings. The saddle 7 is also provided with 'the usual endless conveyer belts 9 located on each side thereof slightly below the apex and traversing the exterior of the saddle in the forward direction but'returning underneath the saddle. The conveyers 9 are carried by suitable small pulleys 10 suitably journaled the saddle 7 and also by larger and additional pulleys 11 mounted on a drive shaft 12, the latter being journaled at one end in a yoke 13 mounted on a standard 13 carried by the front cross bar 5 and at the other end in a member 13 carried by a bracket projecting outwardly from the cross bar 5. The pulleys 10 extend through vertical openings formed on the sides of the saddle 7 as illustrated for transferring the conveyer from the exteriorto the An additional continuous conveyer 14 is illustrated on the rear end of the. saddle which is mounte'dto traverse the apex thereof and to drive a gripping idler pulley 15, the latter being loosely mounted on an adjustable arm 16 and being ed just above the saddle 7 and parallel therewith are two folding rollers 17 and 18,

.sc-ribed. Mounted on the a pair of end standards 24 w .which are ment to these rollers being conveniently journaled in the end cross bars 4. These rollers are adapted to be continuously driven and are geared together to cause one to rotate counterclockwise while the other rotates clockwise, this gearing comprising intermeshing pinions 19 on the forward ends thereof. Extendinglengthwise of the machine is a cross bar 20 which is carried by the't-ransverse cross bars 4 and throughout the length of this cross barare mounted a series of pulley supporting brackets 21, the latter carrying small pulleys which cooperate with the roller 18 to carry a series of horizontally disposed conveyer tapes 22. In the specific embodiment shown there are illustrated seven of these tapes shown in dotted lines 1n Fig. 1. These tapes are spaced apart a predetermined distance to accommodate hereinafter detop of the sup porting framework is a receiving receptacle therebetween apparatus 4 or bin 23 mounted lengthwise of the machine and bridging the cross bars '4. The receptacle designated generally b 23 comprises ich rest on the cross bars 4 and carry from the upper ends thereof horizontally disposed brackets 24% The standards 24 and brackets 24* are bridged respectively by pairs of cross pieces 25 and 25 extending lengthwise of the machine, and each. pair of cross pieces carries a series of vertically disposed panels 26 and 26, this arrangement forming a rectangular bin or receptacle which is open both at the top and the bottom for the reception and removal of folders or booklets. The conveyer tapes 22 as. illustrated extend beneath the receptacle and are adapted to receive the foldersfrom the saddle 7 and convey them to a position from which they are elevatedto the receptacle. Mounted on the lower ends'of the panels 26 is a series of fingers-27 pivoted thereto for pivotal movement in a vertical direction from the horizontal but limited in their downward moveprevent movement below the horizontal. As illustrated in Figs. 5 and 6 this is accomplished by the rearend of the finger engaging a suitable shoulder 28 upon the lower end of the panel. Each panel 26 has fixed to the side thereof a spring 29- which has its free end bent at right angles thereto and passing through an opening 30 in the panel in .the path'of the finger 27, the ar-. rangement being such that the finger 27 engages the spring 29 in its upward pivotal ceptacle 23. The

' a multiplicity back to the normal orhorizontal position when the actuating force is removed. The

set of anels 26 adjacent to the rollers 17 and 18 is provided with a series of guards 31 which are mounted on the lower ends thereof in alinement with the horizontally disposed fingers 27 whereby the folders or booklets are guided and. directed on to the conveyors 22 in their travel to a point beneath the reguards 31 extend above and adjacent to the rollers 17' and 18 and therefore are adapted to engage the folders when they emerge upwardly from between the rollers and guide them'onto the conveyer 22. Additional guards 32 are mounted at intervals along a cross piece 33, the latter extend:

ing lengthwise of the machine and resting in turn 1s carried by the front cross bar 4.

As illustrated in Figs. 3 and 4 these guards 32 extend over the roller 18 and in proximity to the periphery of .the roller 17, these guards or guides 32 being curved or bent downwardly in the manner illustrated to insure the folders following the predescribed path over the roller 18 and conveyer tapes 22. Mounted beneath the saddle 7 and adapted to play in and through the apex thereof are. of vertically knives 35, these knives being frame 36 having vertically disposed guide bars 37, the guide bars 37 in turn beingcarrled in suitable vertically disposed guideways in the brackets 38 e xtendlng inwardly from the cross bars-5. The guide bars 37 are provided with vertically elongated slots 39 for the passage therethrough of one of the conveyer belts 9. he guide bars 37 also are provided on one side thereof with rack teeth for mesh with spur gears 40-mounted on a shaft 41 extending longitudinally of the machine and journaled in the cross bars 5, only oneof these pinions 40 being a parent in the drawings. The shaft 41 on its forward end carries a spur pinion 42 which meshes with a larger pinion 43 -journaled on :1. depending bracket carried by the-front cross bar 5. The gear 43 in turn'meshes' with a vertically reciprocating rack 44 which is mounted in vertical guideways 44 formed on a casting integral with the cross bar 5. Mounted on one of the cross bars 6 extending longitudinally of the machine is a bracket 22 and is adapted to be reciprocated vertically to a position above the conveyer belts or tapes and fingers 27 or to a position be low the conveyers, the arrangement being such that the fingers clear both the conveyers and the panels 26 and 26 during the reciprocation.

The stacker head 47 is adapted to be reciprocated vertically by a shaft 50, the latter having a pinion thereon in mesh with the rack 46 (Fig. 4). The shaft in turn is oscillated from the shaft 41 through aspr'ocket and chain gearing, the sprockets a gearing 56. The inner end of the shaft 55 carr es a bevel pinion 57 which meshes with a similar pinion on the shaft 12 for driving the pulleys 11 and the continuous conveyor belts 9 andv 14. Intermediate its ends the shaft 55 carries a pinion-58 which meshes with the largeidler59 carried on a'bracket depending from the cross bar 4. l

25 is provided on The idler 59 in turn meshes with small spur roller- 18, this small pinion in turn meshin "with a similar pinioni on the roller 17. herollers 17 and 18 and conveyer tapes 22 are thereby continuously driven fromthe motor'and counter-shaft 55.

pinion 19 on the The idler59 ismounted on a countershaft 60 and on the outer end of theshaft'SO is fixed asmall pinion 61,-which in turn meshes with a-large spur. gear 62 loosely mounted upon the reduced end forming the shaft 18 of the roller 18,-the shaft 18 projecting forwardly of the machineand suitably journaled in the cross bar 14.- Secured to the hub of the gear 62 1s .acain 63 coiiperating with arolle 65 j'ournaled on a stu'd64 carried by the rack 44. By means of this rotating cam and the roller 65 the rack 44 is periodically caused tirassuine its maxi mum height A suitable roller 66 mounted on a's't ub axle fixed to'oneof the cross bars the opposite. side of the rack from the cam 63 and roller 65 to receive the thrust and to maintain the rack in proper alinement. In order to maintain the rack is provided which is adapted to engage a shoulder 68 on the upper end ofthe rack, the pawl 67 being urged into engaging relation at all times by is pivoted to the bracket 34 mounted on the top of the cross bar 4 and has a downwardly depending spring arm 69, the spring arm 69 projecting downwardly through a slot in the 44 in the elevated position a pawl 67 gravity. The pawl 67 the shoulder 68 of 49 are positioned apex of the saddle 7 and in the path ofmovement of the folders while being conl able speed and cause a rapid movement of the folder or booklet. The forward end 'of the folder or booklet engages the spring arm 69 depending downwardly in its path and bends the same to the dotted position illustrated in Fig. 1. For preventing the rebound of the folder a resilient member 70 is mounted in thepath of movement of the folder and is caused to engage the rear end of the folder when the limit of movement is reached, the member 70 being mounted on an adjustable arm 71 to accommodate the apparatus to difi'erent folder lengths. Upon the bending of the spring arm 69 and thereb putting the same under tension the pawl 67 is caused to be disengaged from the rack .44 or is caused to move out of the path thereof to the dotted position shown leaving the rack 44 free to recedeto the lowermost position while the cam 63 is making one turn. Inorder to facilitate the disengagement of, the pawl 67. from the tooth or shoulder 68 the arrangement is such that the cam 63 slightly raises the rack 44 out of engagement wit the pawl 67 ,at each turn thereof. Upon the release of-the rack .44 the same falls by gravity to its lowermost position, this movement being hastened by the weight or mass of the stacker head 47 which also falls. by gravity and causes the elevation of the racks 37 together with the knife frame 36. It is understood that the combined weight of the rack 44 and, the stacker head 47 which are geared to move in the same direction 35 are illustrated in- Fig. 4 and in this position it is noted that the stacker head fingers below the upper sides of the conveyer tapes 22 to permit the folders or booklets to be positioned thereover by the tapes. The knives 35 engage the middle of the folders-and urge them upward between the folding rollers 17 and 18 which are rotated at a rapid rate. The guards or guides 31 and 32,direct the folded booklets onto the tapes 22 as heretofore set forth and the booklets are conveyed to a point in register.

with the stacking bin 23. It is noted that the panels 26 below the level extend downwardly to a point at the tapes 22 and thereby v arrest the forward movement of the folders.

The stacker head 47 and knives 35 remain in the positions illustrated in Fig. 4 only while the cam 63 is making one turn, this time being entirely suflicient to remove the folder from the saddle 7 to theposition above the stacker head .47. l/Vhen the cam 63 makes this elevation of the stacker head 47 carries l with a series into the stacking bin 23 past the fingers 2 these fin ers serving to retain the.folders therein. 'I he booklets are thus folded and the air expelled therefrom in an the folder up efiicient manner and the same are stacked' automatically within the bin 23 to be removed at the leisure of the operator. It

should benoted that the tripping arrangement is such that the pawl 67 cannot be released until the rack by the cam 63, the pull of the spring arm 69 under tension being insufficient to cause disengagement of the pawl. Each folder therefore is insured the time of a complete turn of the cam for transfer from the saddle to the bin.

For limiting the downward movement of the rack 44 a bumper 72 is provided which comprises a pad of yielding material 73, as of leather, a bolt 74 being provided through the support 72 for adjusting the vertical position of the pad. By adjusting the downward movement of the rack 44 the upward movement of the knives 35 may be limited to any degree. It is noted that the knives 35 may be adjusted to different points along the frame 36, the frame 36 being provided of apertures throughout its length for the reception of fastening screws. The rear knives on this frame may therefore be entirely removed or adjusted to different distances from the rear end of the machine thereby varying the distance the folder has to travel'in coming from the machine 1 before it reaches the knives and rendering unnecessary 'an increase in speed of the machine to clear the knives out of the way of the advancing folders. It is noted too that while the force of gravity is used in lowering the rack 44 and the stacker head 47 it is obvious that other and positive actuating means maybe used instead. It is also noted that the stapling and stitching machine 1 is for illustrative purposes only and that the present invention is capable of embodiment in machines for various uses and in combination with various machines.
